The profit earned by the sales division of a company each year can be modeled by the polynomial x - x2 + 2x - 100, where x is the number of units sold. The
profit earned by the manufacturing division can be modeled with the polynomial
x2 - 4x - 300.

if you need just tell me and i will come to the rescue.

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

-1   1/6.   you dont subtract the denominators
